A faulty celcius thermometer read 0.7 degree celcius at the melting point of pure ice and 99.5 at the boiling point of water at normal pressure.

Question

Calculate the correct temperature when it reads 30 degree celcius.
At what temperature will its reading be exactly correct

Answer 1

99.5-.7 = 98.8

so
Reading C = Cr = .7 +(98.8/100) C

if Cr = 30
30 = .7 + .988 C
C = 29.7

if the same
C = .7 + .988 C
.012 C = .7
C = 58.3 degrees C or Cr
